I cannot connect to my email through Windows Live Mail 2011 at all.  The program tries to connect and authorize but never completes.  I have confirmed ports and settings with Comcast twice.  I have turned off my virus protection software, and then tried to completely uninstall the Norton program but neither of those steps had any effect.  I receive the following error message each time I try to open my email:

Unable to send or receive messages for the Comcast .........  account. Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity.

Server: 'mail.comcast.net'
Windows Live Mail Error ID: 0x800CCC0F
Protocol: POP3
Port: 995
Secure(SSL): Yes

Please help!
